Influence of Current Density on the Morphology and Structure of Silver Nanoparticles on Anodized Titanium for Biomedical Implant Applications

Abstract

This article focused on investigating the influence of current density on the morphology and structure of silver nanoparticles (n-Ag) electrodeposited on anodized titanium substrates (denoted as TiO2/Ti) on the surface. The TiO2/Ti substrate served as the cathodic electrode placed in an electrolyte solution containing ionic [Ag(NH3)2]+ complex solution. The n-Ag/TiO2/Ti samples were synthesized at current densities ranging from 0.2 A/dm2 to 0.5 A/dm2 for 20 seconds at room temperature. The study performed morphological and surface composition analysis of n-Ag/TiO2/Ti using Field Emission Scanning Electron Microscopy (FESEM) and X-ray Diffraction (XRD) techniques. Additionally, the study assessed the electrochemical properties using the AutoLab system with Nova 2.1 software, based on Tafel curve measurements to compare the corrosion resistance of the samples before and after modification.
